Virtual Reality

3. What Is
Virtual Reality
 Virtual reality is an artificial environment that is created with
software and presented to the user in such a way that the
user suspends belief and accepts it as a real environment.
 Virtual reality (VR) means experiencing things through our
computers that don't really exist.

4. virtual reality is primarily
experienced through two
of the five senses:
sightand sound

5. In technicalterms…
 Virtual reality is the term used to describe a three-dimensional,
computer generated environment which can be explored and
interacted with by a person.
 That person becomes part of this virtual world or is immersed
within this environment and whilst there, is able to manipulate
objects or perform a series of actions.

6. Types of Virtual reality :
Non-Immersive Semi-Immersive Fully-Immersive

7. Non-Immersive : Non-immersive
simulations are the least
immersive implementation of
virtual reality technology.
Users enter into these three-
dimensional virtual environments
environments through a portal
portal or window by utilizing
standard high resolution
monitors.

8. Semi-immersive simulations :
provide a more immersive experience,
experience, in which the user is partly
partly but not fully immersed in a
virtual environment.
Semi-immersive simulations are
powered by high performance
graphical computing systems, which
which are often then coupled with
large screen projector systems or
multiple television projection systems
systems to properly stimulate the user's
user's visuals.
Example: Flight simulator

9. Fully-immersive simulations :
provide the most immersive
implementation of virtual reality
technology.
Fully immersive simulations are able to
able to provide very realistic user
experiences by delivering a wide field
field of view, high resolutions, increased
increased update rates (also called
called refresh rate), and high levels of
levels of contrast into a user's head-
head-mounted display (HMD).
Example: Medicine for Cancer

10. Key Components in a Virtual Reality System :
PC (Personal Computer)/Console/Smartphone
Head-Mounted Display(HMD)
Input Devices:
• Joysticks
• Data Gloves
• Force Balls/Tracking Balls
• Controller Wands

11. Key Components in a Virtual Reality Headset
Sensors
Magnetometer - The magnetometer tells your device which
direction it is facing on the surface of the earth. The
magnetometer acts as a sort of compass for the device.
Accelerometers - The accelerometer tells your device
which way up it is. To do this, your device will have several
accelerometers to work together measuring things like
gravitational pull in relation the accelerometer measuring the
device’s orientation.
Gyroscopes - A gyroscope calculates the orientation of
your device. It does this to either help your device maintain a
particular orientation or make sure it properly changes
